  • Enhanced load distribution from the 0.52" flange diameter, reducing the risk of material damage and improving joint integrity.
  • Secure thread forming with Type A tapping method, creating strong, vibration-resistant threads without pre-drilled tapping in sheet metal.
  • Full threading and pointed tip for easy insertion and maximum grip along the entire 1" length, speeding up assembly processes.
  • Compliance with RoHS 3 and REACH regulations, ensuring environmental safety and suitability for global industrial standards.
  • Right-hand threading with 10 threads per inch provides consistent, precise engagement in 0.242" diameter applications.
  • Durable construction for demanding environments, offering long-lasting performance in sheet metal fabrication and assembly.

Professional Applications & Engineering Value

This No. 14 thread forming tapping screw is engineered to address common challenges in sheet metal fastening, such as material cracking and loosening under vibration. The thread forming design eliminates the need for separate tapping operations, reducing installation time and costs while creating strong, permanent threads. With a fully threaded shank and external hex drive, it ensures maximum clamping force and ease of use with standard tools. Ideal for HVAC, automotive, and electronics enclosures, this screw's flanged head and precise 10 threads per inch enhance load distribution and resistance to pull-out, making it a reliable choice for high-performance industrial assemblies.

Specification Summary & Compliance

This screw features a No. 14 size with a 0.242" thread diameter, 1" length, and 10 threads per inch in a right-hand direction. It adheres to standard inch measurements and includes a 3/8" hex head and 0.52" flange diameter for consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures it meets stringent environmental and safety regulations, supporting use in eco-conscious manufacturing processes.
